Abstract
A portable electronic device has an outer shell, a first speaker assembly, and a second speaker assembly. The first speaker assembly has a first speaker, a first speaker chamber, and an outer edge. The second speaker assembly has a second speaker, a second speaker chamber, and an outer edge. The first and second speaker assemblies are capable of being in a normal position, where the first speaker assembly outer edge and the second speaker assembly outer edge are substantially flush with the outer shell of said portable electronic device. The first and second speaker assemblies are also capable of being in an extended position, where the first speaker assembly outer edge and the second speaker assembly outer edge extend beyond the outer shell of the portable electronic device. Preferably, the first and second speaker chambers each have a larger volume when the first and second speaker assemblies are in the extended position than when they are in the normal position. This larger volume allows for higher quality sound--especially lower frequency sounds--to come from the portable electronic device when the first and second speaker assemblies are in the extended position. Preferably, th…
